PD-RIV Sensor

PD-RIV Sensor

The PD-RIV Sensor is a device for evaluating partial discharge (PD) and radio frequency interference (RIV) currents in electrical assets. With oil or epoxy insulated capacitors and phase voltages ranging from 13.8 kV to 500 kV, it is versatile for indoor or outdoor use. It has comprehensive applications including generators, transformers, high-voltage conductors, reactors, circuit breakers, and capacitors. As the sole national manufacturer of this equipment, HVEX offers customization according to customer needs. The non-invasive electrical method detects early dieltric faults in insulating materials, crucial for early diagnosis of potential decreases in dielectric withstand of assets. With its high-frequency measurement system and dedicated software, it provides precise and reliable results, essential for promoting asset safety and efficiency.

Dielectric Evaluation

Electricity handling relies on the conductive and dielectric capabilities of materials. Dielectric materials have relative insulation and can be breached by high voltages or prolonged periods of time or aging, leading to partial discharges that stress the material. The PD sensor assesses the presence and severity of these discharges by connecting to a transformer bushing via a capacitive coupler or adapting to other equipment. HVEX utilizes the capacitive electrical method to measure partial discharges, filtering and treating discrete pulses to provide results on the severity of partial discharges. Meanwhile, radio interference voltage (RIV) testing verifies whether the equipment operates without distortions in environments exposed to electromagnetic fields, evaluating the response signal by an oscilloscope after passing through filters and dividers. The PD-RIV HVEX Sensor is the ideal choice for accurate and reliable assessment of partial discharges and radio frequency interference voltage (RIV), ensuring safety and efficiency across various applications
